Parameterized testing tools with automatic code exploration

Question

I've checked and played a bit with Microsoft Pex. It's a very handy tool/library even though it's not as straight forward to write parametrized unit tests with it. But when used correctly it can provide much better test code coverage than writing manual unit tests. Not to mention time spent writing those tests either. And it integrates nicely with Visual Studio as well.

I was wondering whether there are any other tools out there that let you write parametrised unit tests and run them so internal algorithm intelligently chooses values to provide full code test coverage?

If some other tool/library was as easy to use as NUnit+Moq I'd be even more pleased. Pex has quite a steep learning curve (so does Moles I suppose).

Are there any plans for NUnit to support parametrised tests with inteligent parameter choosing in the future maybe? Anybody has any inside info about it?

Answer 1

If you're looking for other automatic testing tools for .NET, take a look at FsCheck. It's a port of Haskell's QuickCheck to F#. It's also usable from other .NET languages.

QuickCheck has also been ported to other platforms (ClojureCheck, ScalaCheck)

*Check libraries are not exactly like Pex, but there are similarities.

If you mean parameterized tests for .NET (as in writing tests that take parameters), all major test frameworks in .NET (NUnit, MbUnit, xUnit) support this.
